ros2 service list Colorization

When you run ros2 service list, DendROS automatically colorizes the output using the same group colors and badges configured for ros2 launch. Standard ROS 2 system services are dimmed so your own services stand out.

What gets colored

Custom services

Services that belong to a node in your config are colored with that node's group color. The owning node is inferred from the service path — for /talker/my_service, DendROS looks up /talker in the color map using the same four-tier matching as ros2 node list (exact path, basename, wildcard path, wildcard basename).

A group badge is shown to the left of the service path when show_tag_cli is enabled and the group has a label.

Default (system) services

Every ROS 2 node automatically creates a set of standard parameter and logger services. These are rendered dimmed so they stay visible but don't compete with your own services:

  • describe_parameters
  • get_parameter_types
  • get_parameters
  • list_parameters
  • set_parameters
  • set_parameters_atomically
  • get_loggers
  • set_logger_levels
  • get_type_description

When the owning node has a color configured, the name is dimmed in that color (node_color + dim). Otherwise it falls back to plain dim.

Hiding default services

If you want to declutter the output entirely, set show_default_services: false in ~/.config/dendROS/defaults.yaml (or toggle it in dendros config). Default services will be omitted from the output completely.

Type annotations (-t)

Running ros2 service list -t appends a type annotation to each entry:

/talker/my_service [custom_msgs/srv/MyService]

The type content inside the brackets is always dimmed, keeping the focus on the service name.

Badge and style options

Setting Effect on service list
show_tag_cli: true [LOC] /talker/my_service (badge always to the left)
tag_style: inverted Badge rendered with colored background
Per-group show_tag: false Badge suppressed for that group only
unmatched_color Services with no matching node shown in the fallback color
unmatched_tag Badge shown next to unmatched services (requires unmatched_color)
dim_unmatched Services with no matching node dimmed (only when unmatched_color: null)
show_default_services: false Default system services hidden entirely
